SEAL- ESPECEFEGATIN forming part of Letters Patent No. 334,407, dated Jauuary 19, 1886.

Application filed October l, 1885. Serial No. 178,700.

To all whom t may concern:

Beit known that we, GEORGE H. ANGELL and CHARLES L. LESLIE, citizens ofthe United States, residing at'Omaha, in the county of Douglas and'Stateof Nebraska, haveinvented certain new and useful Improvements in Seal-Loeks, of which the followingisaspeciication, reference being hadtherein to the accompanying drawings.

Oui invention relates to improvements in car-sealing or seal-fasteningdevices by which said fastening cannot be opened without indicating thesame to have been done.

Our improvement consists in the mechanism illustrated in theaccompanying drawings, in which- Figure l is a face view of a seal-lockconstructed in accordance with our invention; Fig. 2, a vertical sectionof the same; Fig. 3, a side view of the same; Fig. 4, a rear View of theface-plate; Fig. 5, a horizontal section of the lock; Fig. 6, a top viewof said lock. Figs. 7 and 8 are front views of sealing-cards used withthe lock. Fig. 9 is a front perspective view of the lower portion of theback plate of the lock. Fig. 10 is a horizontal section of the front andback plates and sealing-card on line x x of Fig. 2. Fig. 1l is aperspective view of a knife-plate carrying two blades. Fig. l2 is afront view of a slightly modified form of our lock, in which the knifeprojects from the rear ofthe sliding front plate. Fig. 13 is a side Viewof the same. Fig. 14 is atop view of the same.

The back plate, A', of the lock has generally projecting from its upperend an arm, A,

bent in the form of ahook, having its free end extending forward of theback plate and entering a socket, B, formed for its reception in theupper front portion of the face-plate F. From the lower portion of saidface-plate projects a lug, C, by which the face-plate can be drawndownward to withdraw the end of the hook from its socket and open thelock.

From the rear of the back plate projects a perforated lug, D, to retainone end of a chain to fasten the lock to a car.

The back plate,A,has its vertical edges provided with grooves A toreceive the edges of the front plate and permit the latter to slide fora limited distance in said grooves, said distance being sufficient topermit the sealing- (Model.)

l card E to be placed in position when the front plate is open to itsextreme lower limit.

Frein the lower portion of the back plate, A, projects toward the frontthe knife H, having its edge upward, against which the sealing-cardrests when the seal is closed. This knife can be either rigidly securedto the back plate, in which case the sealing-card has to'be slightlysprung or bent vertically to insert it past the knife into the lock, orthe knife or knife-blades can be mounted on a spring or secured to athin steel plate, h, retained by screws passing through slots thatpermit it to spring back against the back plate while entering thesealing-card into the lock. This arrangement may be reversed, and theseat for the card and the knifeway may be in the back plate, as shown inFigs. l2 and 13, and the knife H'l be secured to the rear of thefaceplate to rest upon the top edge ofthe sealingcard and cut the lattervertically in two from top to bottom before the lock can be opened.

For the passage of the knife H, attached to the back plate, averticalgroove or knifeway, I, is formed in the back of the front plate. Thisplate is also provided with a rectangular recess, F2, 'to retain inlposition the glass or transparent covering G ofthe seal,and a larger butless deep recess, F3, to receive the sealingcard E.' The sealing-cardmay be composed of paper, cardboard, wood, lead, or of sheet metal-astin, brass, copper, Ste-and made of such width, length, and thickness aswill fit snugly in the receptacle F3 provided for it in the lock, and becut or tornin two or more separate parts while forced against the edgeof the knives. The sealing-card may be made with a portion punched outnear its lower edge, as shown at c in Fig. 7, through which the knife Henters in position to cut or tear through the balance of the card,leaving a marginbelow to hold the parts of the card together. Thesealing-card bears printed or stamped inscriptions and numbers, fromwhich it can be recognized. Thereis an opening, F, in the face-plate,through which and its glass G the sealing-card can be seen, and anytampering with the lock be discovered.

We are aware that seal-locks have been formed with a hollow bodycarrying therein a pivoted knife, and a shackle passing through saidbody and having a recess for the recep- IOO tion of a card adapted tobear against the edge ofthe knife, and do not elaini this construe tion.Neither do We elaini a seal-lock provided with a bolt Carrying` a knifeat its outer end in connection with a easing containing a card to besplit by said knife in opening the lock.

Having now fully described onr invention, whatwe claim, and desire tosecure by Letters Patent, is-

A seal-look consisting,` of two plates ofnietal, the front one of whichis adapted to slide vertieally in grooves Within the back plate and isprovided with a projecting` lng on the front
